This call for a watch on the East coast was based upon the craton edge movement to the West…… in Oklahoma, Texas, and Wyoming.

This South Carolina Earthquake was the result of massive pressure building across the Southern Edge of the plate ( pressure coming from the West) showing up as heavy earthquake activity in Oklahoma / Texas , at the fracking operations.

When we see large movement in the Midwest we can now (for sure) take this as a PRECEDING SIGN of possible coming East coast seismic movement.
